Exchange rate problem

[#1]

Hi,

I have problem with exchange rate. I have two tables A (order_number, order_date, currency) and B (date, currency, exchange_rate). I created key (date&currency) and it's working perfectly, but..

On each Monday I don't have exchange rate value, becaus it's announced on Tuesday. In this case I sholud use exchange rate from last day when it was announced (in this case from Friday). How to do this?

I need this value when I create a straight table and I'm converting currency:

if(Currency<>'PLN',[Ordered quantity]*[Purchase price]*[Exchange rate];[Ordered quantity]*[Purchase price])

Hi,

You can do something like this:

load

     if (isnull(exchangerate) and day=monday,above(exchangerate,3),exchangerate) as exchangerate

succes!

Hi,

function above() is not working in script, but I can use it in straight table.

I have one more problem. I noted that if in tabel with EX_RATE exchange rate don't exist then I can't use it as key.

Please, look to example below. In straight table 'ORDER VALUE' I would like to have position for date 20111017 and currency EUR,

which consist in column exchange rate value from day before (in this case from 20111014).

Sorry,

You have to use previous() in the script.

I would not use above() in the table, because when you select one day, a monday, it is not working fine.
